The hint is visible wherever autocomplete suggestions are shown.<\/li>\n\n\n\n<li>Added &#8220;Powered by WProofreader&#8221; branding to the suggestion pop-up for the browser extension, WordPress plugin, and Drupal integration.<\/li>\n\n\n\n<li>Redesigned the promotional banner in the free SCAYT plugin for CKEditor 4.

This replaces the previous bigram-based approach and improves the accuracy of spelling suggestions by considering three-word sequences instead of two. When multiple spelling candidates are equally plausible \u2014 e.g., <em>store<\/em>, <em>shore<\/em>, <em>stare<\/em> \u2014 the model uses surrounding context to rank the most relevant suggestion higher. In benchmarks on American English, the correct suggestion now ranks first approximately 80% of the time, compared to 71% with the previous approach. Each language model requires approximately 100 MB of RAM. Currently, only suggestions from the main algorithmic spelling engine are reordered by the n-gram model.<\/li>\n\n\n\n<li>Expanded dictionaries with 2,000+ new entries across multiple languages (including English, German, Spanish, Ukrainian, Danish, Portuguese and Finnish). This covers a broad spectrum of categories: abbreviations (shortened forms), affixes, biology, business, chemistry, common terms, culinary, dialectal variations, legal, locations, neologisms, proper names, religion, science, slang, sport, and technology.<\/li>\n\n\n\n<li>Refined word lists by removing invalid dialectal entries, nonexistent words generated by compounding mechanisms, and incorrect casing.<\/li>\n\n\n\n<li>Enhanced medical terminology across English, Spanish, and German with 600+ new entries covering medical abbreviations, adjectives, disease names, and measurements.<\/li>\n\n\n\n<li>Optimized split patterns by adding 20+ rules for common words, adverbs, and conjunctions to prevent incorrect word splitting, while removing outdated or less restrictive patterns.<\/li>\n\n\n\n<li>Improved suggestion quality by excluding offensive terms in certain contexts and removing company names that overlap with common English words.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-grammar-engine\">\u2699\ufe0f Grammar engine<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Updated the third-party grammar engine, LanguageTool, to version 2026-02-13 with improvements across multiple languages.\n<ul class=\"wp-block-list\">\n<li><strong>Portuguese.<\/strong> Extensive updates including new academic and formal style rules, improved handling of agreement, contractions, homonyms, and commas, disambiguation refinements for rare verbs and part-of-speech tagging, and numerous false-positive reductions.
